A fitness studio is not a real-estate business — it is a retention business wearing a lease. The cost structure is forgiving on paper (no food waste, no inventory markdowns) but unforgiving on churn: lose members faster than you sign them and the fixed rent wins.

The studio cost stack

LineHealthy range (% of revenue)
Trainer / coach pay (labor)25-35% (some models 20-44%)
Rent / occupancy12-20% (metro 25%+)
Marketing & acquisition5-12%
Net margin (sustainable)15-30%

Net margin varies sharply by model: boutique 20-40%, personal-training studio 30-50%, CrossFit 15-25%, traditional gym 10-15%. The sustainable band for a well-run independent studio is 15-30%.

The two numbers that decide everything

Monthly member retention90-93% healthy
Revenue per square foot / month$8-$12 (top $15-$25)
ARPM (avg revenue per member/mo)$110 boutique, $49 24/7, up to $180
Pre-sale compresses break-even: a membership pre-sale can pull break-even from 6-18 months down to 3-8 months, because you fund fit-out with committed members instead of debt. Most closures come from opening cold with no base.
